[0002] Low-voltage switchgear is a combination that includes one or more low-voltage switchgear and related control, measurement, signal, protection, regulation and other equipment. The manufacturer is responsible for completing all internal electrical and mechanical connections of these equipment and assembling them completely with structural components. Low-voltage switchgear is suitable for a variety of industries, such as power plants, petroleum, chemical, metallurgy, textiles and high-rise buildings, and is mainly used for power transmission, distribution and power conversion.

[0003] After searching, the utility model patent with Chinese patent announcement number CN215119754U discloses a low-voltage switch cabinet, which belongs to the technical field of power equipment. A low-voltage switch cabinet includes a cabinet, a bottom plate, a back plate, a slide bar and a buffer assembly. The bottom end of the cabinet is provided with a buffer assembly, and the buffer assembly includes a spring of a support plate. The top of the support plate is fitted with the bottom end of the cabinet, and the bottom end of the support plate is connected with a spring. The other end of the spring is provided with a bottom plate, and the side wall of the bottom plate is provided with a back plate. The side wall of the back plate close to the cabinet is provided with a slide bar, and the side wall of the cabinet close to the back plate is provided with a slide rail matched with the slide bar. The bottom plate and back plate provided on the low-voltage switch cabinet can separate the cabinet from the ground and the wall, and can effectively prevent the moisture on the ground and the wall from corroding the cabinet. The slide bar and the slide rail on the cabinet cooperate with each other, so as to facilitate the rapid installation of the cabinet. The setting of the limit pressing buckle can effectively prevent the cabinet from moving up and down along the slide bar.

[0004] After searching the above patents, it was found that the installation of the low-voltage switch cabinet was processed. However, the low-voltage switch cabinet failed to process the heat dissipation and fire extinguishing of the electrical equipment installed inside, which easily led to the high temperature environment accelerating the aging of the electrical equipment and affecting its service life. At the same time, overheating caused the performance of the electrical equipment to decline and even caused failures. At the same time, when the equipment was running, it was easy to cause a fire due to short circuit, overload or poor contact. If the fire was not extinguished in time, it would easily cause the fire inside the low-voltage switch cabinet to spread, increasing the risk of casualties. At the same time, the smoke and toxic substances generated by the fire would pollute the environment. Utility Model Content
